Thanks for your interest in our listing. We’re a husband and wife team and we love helping people find things they love! Any questions at all, just ask! 😁 The tag is very hard to read. It does show that the neck is size 17. The chest measurements are 46” inches, so we’re listing it as a size Large. There is a small gray mark on the collar that I have pointed out. See pictures for sizing, measurements, and pictures of tags. Please measure your favorite item and compare our pictured measurements with your item to ensure a great fit for you.
